Was in a chippy today and wanted large cod and a cone of chips.
I had just a fiver but noticed the cost was £5.20 so i asked the server if i could have 50%less chips and pay just the fiver.
She consulted the boss who refused... So i walked and spent my money elsewhere.
It reminded me that it doesn't matter what business your in, if you are unable to make a compromise then your customer will go elsewhere
For the sake of 20p they lost my £5 plus any future business, yet if they had accepted my offer i would have returned and the goodwill created would have been immense (as well as my belly)
